Weather and climate prediction on next generation supercomputers

Workshop theme

Satellite Meeting at the Met Office

Ever increasing model complexity and more and more complex scientific questions are demanding higher resolution and wider process coverage. This leads to a seemingly insatiable appetite for computational resources amongst the weather and climate modelling community. This significant challenge is elevated to a new magnitude if combined with the pressures and requirements of operational centres with regard to reliability of the compute platforms, models and scientific quality of the results. This appetite can potentially be sated by the next generation of supercomputers with their step change in core counts and use of accelerators. But utilisation of these new machines demands a step change in the scalability of the code and in parts major rewrites of existing code and formulations.

This workshop aims at bringing together key players of the academic, operational NWP/climate and high performance computing communities. This meeting will address the problems, challenges and predictions for the future in order to guide development and raise awareness for limits ahead and possible routes for their mitigation, enabling future collaborations and joint developments.

The main topics to be covered are:

State of the art in weather and climate modelling, where we came from and where we want to go
Discretisations, equation-sets, grids and solvers for the resulting systems
Operational aspects of weather and climate modelling
Computational trends, limiters and opportunities

Addittionally, there will be ample time for contributed talks from workshop participants. Please email markus.gross[at]metoffice.gov[dot]uk to submit title and abstract of contributed talks no later than July 2012.

Applications for this workshop are now closed
